To truly test the capabilities of the Sound Blaster X7 and the quality of the audio reproduction, our team
performs listening tests with a variety of genres and with different pairs of headphones. We do not believe in
limiting ourselves to just gaming demos, but to achieve a more critical assessment, we use Industry Reference
Tracks for the auditions. For an inclusive listening experience, we also do not confine ourselves to using just our
signature Aurvana Headphones, but have included in our tests the Fostex T50RP Critical Listening Headphone
as well as the Beyerdynamic DT880 (600 ohms) headphones among others.
What has the award winning German music composer, Mr Hans
Zimmer, to do with games? Well, very much! To bring out the
realism in games, compelling detailed graphics and captivating
audio must go hand in hand. Hans Zimmer’s masterpiece
in Modern Warfare 2: Opening Title is able to draw out the
suspense, fear and heroic spirit of the game. If played on just
measly speakers or average headphones, the soundstage and
presence will never be felt, let alone London Philharmonic
Orchestra’s spectacular scoring for this game. However, when
played through the Sound Blaster X7, the opening piece creates
an ambience that puts you right there in the battlefield! Truly,
music stirs the emotions and in this “Opening Title”, either
courage rises out of you or goosebumps out of fear!
Demo #1: Experience unparalleled realism
Hans Zimmer – Modern Warfare 2: Opening Title
Leona Lewis’s
Bleeding Love
is the top selling single world wide
in 2008. The pop/R&B ballad showcases Leona’s impressive
vocal prowess. Accompanied by church organs, synthesized
strings, wood block percussions and even a distorted marching
drum, this song is brought to a whole new level of rhythm via
the Sound Blaster X7. The Sound Blaster X7 is adept to splendid
displays of contemporary songs as it is for audiophile music and
even music created for games.
Demo #2: Experience powerful vocals
Leona Lewis – Bleeding love
If you have been watching movies on your tablet or smartphones,
you would notice the lack of impact and cinematic audio effects.
Let this demo of the award winning Life of Pi show you what the
built-in SB-Axx1 multi-core processor on the Sound Blaster X7 can
do for your mobile movie experience. Simply push the SBX button
on the Sound Blaster X7 to activate Sound Blaster’s intelligent
processing capabilities and you will be transported into the movie
itself! Experience true-to-life surround sound, enhanced movie
dialogs and minimized volume level changes, just like in the
cinemas. Have absolute audio control over any movie audio using
the Sound Blaster Central mobile app (for iOS and Android) or the
Sound Blaster Control Panel software (for PC and Mac).

SBX Surround – Move the slider higher to “open” up a larger sound field and simulate a surround speaker
setup. A lower percentage gives a more “centered” audio. SBX Surround can be experienced when you plug in
a pair of headphones into the Sound Blaster X7.
SBX Crystalizer – A higher percentage means a larger amount of audio details restored.
SBX Bass – Slide the slider to adjust the enhancement of bass sounds. More harmonic tones will be added the
higher you go. You can also adjust the Crossover Frequency to set the transition of bass.
SBX Smart Volume – Activate Smart Volume to normalize volume levels (Normal), pump up the volume (Loud),
or reduce loud burst of sounds for those late night sessions (Night). Move the slider to adjust the intensity
accordingly.

This document guides you through the set up of your Sound Blaster
®
X7, for RMAA measurement in real-time
24-bit/192kHz Playback and Recording using the Analog Inputs and Outputs. Comparison charts for results of
the 24-bit/44.1kHz, 24-bit/48kHz, 24-bit/96kHz and 24-bit/192kHz. RMAA measurements can also be found at
the end of this document. These Analog I/O tests prove that superb quality analog audio inputs and outputs can
be achieved by the product’s very high quality DAC, ADC and board design.
Setting up Sound Blaster X7 for Analog Measurement
Your Sound Blaster X7 has the unique feature of using hardware digital signal processing to improve audio
quality and listening experience. However, such processing is considered “distortion” by tools designed to test
for audio precision.
Hence, in order to properly measure the Sound Blaster X7’s analog precision, you must first disable all such
processing.
The recommended procedure for disabling such processing is as follows.
1. Launch Sound Blaster X7 Control Panel
The Sound Blaster X7 Control Panel is an application designed specifically for input and output configurations
of the Sound Blaster X7. Navigate to each of the following menu tabs, SBX Pro Studio, CrystalVoice, Scout Mode,
Equalizer, and disable (“Off”) all audio effects from each of these features.

3. Output and Input Setup
• At the Mixer tab, select “Playback” and set the Master Speaker Volume to 100%. Set the rest of the Monitoring
source and SPDIF Out to 0% and mute them.
2. Cable Loopback Connection and Set Impedance
Use a high quality RCA to RCA audio (stereo) cable; connect the Line output to Line Input for the loopback test.
Then set the impedance to 8Ω at the back of Sound Blaster X7.

• Your Sound Blaster X7 is now properly set up for Analog measurement.
• Select “Recording”, set Line In volume at 50%, set all other Recording inputs to 0% and mute them.
4. Setting Up RMAA for Analog Measurement:
• Launch RMAA v6.4.0
The latest version of the RMAA software can be downloaded from the following website:
http://audio.rightmark.org/download.shtml
• Select the bit depth and sampling rate you wish to test. Select a matching sample rate for both the
Speaker endpoint and Line In endpoint at the audio device properties page.

• Establishing playback and recording levels:
Click on this button in the Run tests section,
Adjust the Recording Line-In level (@~50%) till the test tones are ~-1dB.
• Repeat the RMAA test with different sample rate such as 24-bit, 44kHz, 24-bit, 48kHz 24-bit, 96kHz or 24-bit,
192kHz.
• Summary of Audio Settings:
- Master Sampling Rate : Matched to the test performed e.g. 192kHz
- Speaker Mode : Stereo (Spk) for Line Out, Direct Mode On
- Master Volume : 100% (0dB)
- Record Source : Line-In @ 50% (~-1dB)
- All Other Inputs : 0% and Muted
